Ridden and Reviewed: Four E-Bikes

Trek 7200+

1 / 4

The 7200+ is the best-selling model in Trek’s Ride+ line. It uses a punchy 350-watt rear-hub motor activated by a torque sensor that measures your pedaling force and multiplies it by 25, 50, 100, or 200 percent, depending on the setting. We like the LCD-display control, which makes it easy to toggle through power settings. The device also controls the bike’s lights, which are powered by the lithium-manganese battery.
